I'm fairly new with python and am trying to build a fairly simple
search script. Ultimately, I'm wanting to search a directory of files
for multiple user inputted keywords. I've already written a script
that can search for a single string through multiple files, now I just
need to adapt it to multiple strings.
I found a bit of code that's a good start:
import re
test = open('something.txt', 'r').read()
list = ['a', 'b', 'c']
foundit = re.compile('|'.join(re.escape(target) for target in list))
if foundit.findall(test):
print 'yes!'
The only trouble with this is it returns yes! if it finds any of the
search items, and I only want a return when it finds all of them. Is
there a bit of code that's similar that I can use?
[insert standard admonition about using "list" as a variable
name, masking the built-in "list"]
Unless there's a reason to use regular expressions, you could
simply use
test = open("something.txt").read()
items = ['a', 'b', 'c']
if all(s in test for s in items):
print "Yes!"
else:
print "Sorry, bub"
This presumes python2.5 in which the "all()" function was added.
Otherwise in pre-2.5, you could do
for s in items:
if s not in test:
print "Sorry, bub"
break
else:
print "Yeparoo"
(note that the "else" goes with the "for", not the "if")
